E433: Polysorbate 80
Main role: emulsifying
Also listed as: polyoxyethylene sorbitan monooleate, Tween 80
What is E433 (Polysorbate 80)?
Polysorbate 80 is an emulsifier made from modified sorbitan and an oleic-acid component. It helps stabilize mixtures of water and fat and can support consistent frozen-dessert texture.
What does it do in food?
Its main role is emulsifying. Emulsifiers help ingredients mix or remain distributed. The recipe determines whether that means dispersing fat, improving dough handling, or controlling a coating. Their presence alone does not describe the food’s overall nutritional quality.
Food and formulation examples

- Dessert preparations
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E433, E 433, or the ingredient name. Related names and label terms include polyoxyethylene sorbitan monooleate, Tween 80. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Laboratory findings about polysorbate 80 and the gut need context about dose and study design. They are not a diagnosis for someone who has eaten a food containing E433.
Is E433 safe?
The EFSA polysorbates re-evaluation (2015) is a scientific reference for this group. Its conclusions apply to the uses and exposures considered in that assessment, rather than every possible use or personal circumstance.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E433 as Polyoxyethylene sorbitan monooleate (polysorbate 80). This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
